Time is an important aspect of health economic evaluation, as the timing and duration clinical events, healthcare interventions their consequences all affect estimated costs effects. These issues should be reflected in design models. This article considers three aspects time modelling: (1) which cohorts to simulate how far into future extend analysis; (2) simulation time, including difference between discrete-time continuous-time models, cycle lengths, converting rates probabilities; (3)...

Background & AimsNationwide organized gastric cancer (GC) screening programs have been running for decades in South Korea and Japan. This study conducted a quasi-experimental analysis to assess the population impact of these on GC mortality.MethodsWe used flexible synthetic control method (SCM) estimate effect age-standardized mortality other upper gastrointestinal (UGI) diseases (esophageal peptic ulcer) among people aged ≥40 years. World Health Organization data country-level covariates...

To undertake a child-centred evaluation of treatment provision for visible enamel defects.Postal questionnaires, developed with children, were sent to 88 patients, aged 7-16 years, defects permanent incisors and who had received microabrasion, with/without additional composite restoration at Sheffield Dental Hospital, UK. The questionnaires sought children's perceptions about their teeth before after the intervention, as well how they been treated. Anonymised responses graded using 10 cm...

The cost-effectiveness threshold in health care systems with a constrained budget should be determined by the of displacing services to fund new interventions. Using comparative statics, we review some potential determinants threshold, including for care, demand existing interventions, technical efficiency and development technologies. We consider anticipated direction impact that would affect following change each these determinants. Where system is technically efficient, an increase...

The objective was to evaluate whether routine aspirin 75 mg is more cost-effective than the Fetal Medicine Foundation screen-and-treat approach for preeclampsia prevention in low-risk nulliparous women. A health economic decision analytical model devised estimate discounted net and cost outcomes of versus screening test-indicated a cohort 100 000 Both strategies were compared with no intervention. subanalysis also disaggregated components algorithm. analysis used data from hospital...

It is acknowledged that health technology assessment (HTA) an inherently value-based activity makes use of normative reasoning alongside empirical evidence. But the language used to conceptualise and articulate HTA's aspects demonstrably unnuanced, imprecise, inconsistently employed, undermining transparency preventing proper scrutiny rationales on which decisions are based. This paper - developed through a cross-disciplinary collaboration 24 researchers with expertise in healthcare...
